Specifically, as shown in FIG. 3 and FIG. 4, FIG. 3 is a schematic diagram of the child riding device 1 according to the present application. In FIG. 3, when the frame 10 begins to fold, the upper handle 122 and the lower handle 124 of the frame 10 are pivotally folded with each other, and the upper front foot of the frame 10 is The front leg 132, the front leg lower portion 134 and the rear leg 140 are pivotally folded with each other, thereby starting to fold the frame 10. At the same time, the connecting seat folding mechanism 50 drives the connecting seat 30 to start folding. As shown in FIG. 4, as the frame 10 is completely folded, the connecting seat folding mechanism 50 also drives the connecting seat 30 to be in a completely folded state. The folded connecting seat 30 does not occupy additional space and does not cause the volume of the frame 10 in the folded state to increase.

The specific structure of the connecting seat folding mechanism 50 according to the present application will be explained below with reference to FIG. 5 , which is a schematic diagram showing the structure of the connecting seat folding mechanism 50 of the child carrier 1 according to the present application. According to the embodiment shown in the figure, two connecting seats 30 are provided to provide stable and uniform support for the baby basket 2. The two connecting seats 30 are respectively located on the left and right sides of the frame 10, and the pivot point of the connecting seat 30 and the frame 10 is located above the pivot point S4 (see FIG. 6 ). Referring to FIG. 5 , the pivot point of the connecting seat 30 and the frame 10 is located at the inner side of the third pivot point S3 where the front leg upper part 132, the front leg lower part 134 and the rear leg 140 are pivoted. For example, the pivot point of the connecting seat 30 and the frame 10 is coaxial with the pivot point S3. In other embodiments, the pivot point of the connecting seat 30 and the frame 10 is located at the front leg upper part 132 or the rider lower part 124. Correspondingly, two connecting seat folding mechanisms 50 are also provided. In the following description, only one of the connecting seat folding mechanisms 50 is used as an example for description, and accordingly, only one side of the pivot connection relationship is used as an example for description.

The connecting seat folding mechanism 50 includes a driving member 510 and a linkage member 520, wherein a first end 522 of the linkage member 520 is pivotally connected to the front foot assembly 120 of the frame 10, and a second end 524 of the linkage member 520 is pivotally connected to the rider assembly 120 of the frame 10.

The first end 512 of the driving member 510 is pivotally connected to the connecting seat 30, and the second end 514 of the driving member 510 is pivotally connected to the linkage member 520.

According to the embodiment of FIGS. 6A to 6C , the second end 514 of the driving member 510 may also be pivotally connected to the rider assembly 120, for example, the second end 514 of the driving member 510 is pivotally connected to the rider upper portion 122, or pivotally connected to the rider lower portion 124. According to other embodiments not shown, the second end 514 of the driving member 510 may also be pivotally connected to the front foot assembly 130, for example, the second end 514 of the driving member 510 is pivotally connected to the front foot upper portion 132, or pivotally connected to the front foot lower portion 134.

The folding and unfolding actions of the frame 10 will drive the driving member 510 and the linkage member 520 of the connecting seat folding mechanism 50 to pivot, and then the connecting seat 30 can be folded along with the folding of the frame 10 and unfolded along with the unfolding of the frame 10 through the pivoting of the driving member 510 and the linkage member 520.

The following will take the second end 514 of the driving member 510 pivotally connected to the linkage member 520 as an example to illustrate the operation process of the connecting seat folding mechanism 50.

Refer to Figure 6, which is a schematic diagram showing the structure of each pivot point of the child riding device 1 according to the present application. According to this embodiment, the upper part 122 of the rider and the upper part 132 of the front foot are pivoted at the first pivot point S1, the upper part 122 of the rider and the lower part 124 of the rider are pivoted at the second pivot point S2, and the upper part 132 of the front foot, the lower part 134 of the front foot and the rear foot 140 are pivoted at the third pivot point S3.

In addition, the front foot lower portion 134 and the first end 522 of the linkage 520 are pivoted at the fourth pivot point S4, the rider lower portion 124 and the rear foot 140 are pivoted at the fifth pivot point S5, the rider lower portion 124 and the second end 524 of the linkage 520 are pivoted at the sixth pivot point S6, the second end 514 of the drive member 510 and the linkage 520 are pivoted at the seventh pivot point S7, and the first end 512 of the drive member 510 and the connecting seat 30 are pivoted at the eighth pivot point S8.

When force is applied to the upper portion 122 of the rider or the lower portion 134 of the front foot to fold the frame 10, with reference to FIGS. 4 and 6, the upper portion 122 of the rider and the lower portion 124 of the rider are pivoted and folded close to each other through the second pivot point S2, the upper portion 132 of the front foot and the lower portion 134 of the front foot are pivoted and folded close to each other through the third pivot point S3, and the upper portion 132 of the front foot and the lower portion 134 of the front foot are also pivoted and folded close to the rear foot 140 through the third pivot point S3. , and the rider upper portion 122 and the front foot upper portion 132 are pivoted and folded close to each other through the first pivot point S1, and the rider lower portion 124 and the rear foot 140 are pivoted and folded close to each other through the fifth pivot point S5, thereby making the frame 10 folded and folded to the frame folded state shown in FIG. 4; at the same time, because the rider lower portion 124 is pivoted and folded close to the rear foot 140 through the fifth pivot point S5, the front foot lower portion 134 is pivoted and folded close to the rear foot 140 through the fifth pivot point S5. The third pivot point S3 is pivoted and retracted close to the rear foot 140, and the first end 522 of the linkage member 520 is pivoted to the front foot lower part 134 through the fourth pivot point S4, and the second end 524 of the linkage member 520 is pivoted to the rider lower part 124 through the sixth pivot point S6. Therefore, the pivoting and retracting of the rider lower part 124 and the front foot lower part 134 will drive the linkage member 520 to pivot and retract close to the front foot lower part 134. The second end 514 of the bicycle frame 10 is pivoted to the linkage 520 through the seventh pivot point S7, so the pivoting of the linkage 520 drives the driving member 510 to pivot and retract, and since the first end 512 of the driving member 510 is pivoted to the connecting seat 30 through the eighth pivot point S8, the pivoting of the driving member 510 drives the connecting seat 30 to pivot and retract along the arrow direction of FIG. 6 and approach the lower part 134 of the front leg, without causing the occupation of additional volume. In this embodiment, the connecting seat 30 is pivoted to the frame 10 at the lower end, and the upper end of the connecting seat 30 is provided with a clamping portion 38 for mounting the baby basket 2. In the unfolded state, the clamping portion 38 of the connecting seat 30 faces upward (as shown in FIG. 2). 4 , in the folded state, the clamping portion 38 of the connecting seat 30 faces downward. In the folded state of the frame 10, the first pivot point S1, the third pivot point S3 and the fifth pivot point S5 are located above the second pivot point S2, and the third pivot point S3 and the fifth pivot point S5 are located in front of the first pivot point S1 and the second pivot point S2.

On the contrary, when the frame 10 is unfolded, as the rider upper portion 122, the rider lower portion 124, the front leg upper portion 132, the front leg lower portion 134, and the rear leg 140 are unfolded relatively far away from each other, the seventh pivot point S7 and the eighth pivot point S8 drive the linkage member 520 and the driving member 510 to pivot and unfold in the opposite direction, thereby driving the connecting seat 30 to pivot and unfold upward to connect the baby basket 2. In this way, even when the baby basket 2 is removed, the connecting seat 30 is still installed on the frame 10, thereby avoiding the occurrence of loss. At the same time, the connecting seat 30 can be folded along with the folding of the frame 10 and unfolded along with the unfolding of the frame 10 under the drive of the connecting seat folding mechanism 50, which is convenient to use and will not cause the volume of the frame 10 in the folded state to increase.

The child riding device 1 according to the present application may also be provided with a frame folding locking mechanism 60 to lock the frame 10 in the folded state to prevent the frame from being unfolded at will.

For example, the limiting member 1212 is a convex column integrally formed on the outer side surface of the driver's seat 121; correspondingly, a limiting groove 624 (shown in Figure 9) is provided on the inner side surface of the folding locking member 620, and the limiting groove 624 is an arc-shaped groove around the pivot axis. The limiting member 1212 can be relatively movably accommodated in the limiting groove 624. Referring to FIG. 9 , FIG. 9 shows a schematic diagram of the specific structure of the folding locking member 620 of the frame folding locking mechanism 60 according to the present application. In addition to the above-mentioned limiting groove 624, the folding locking member 620 further includes a snap-fitting portion 621 and a pivoting portion 622. The snap-fitting portion 621 and the pivoting portion 622 are respectively arranged at two opposite ends of the folding locking member 620. The folding locking member 620 is installed in the above-mentioned installation recess 1211 via the pivoting portion 622. After the frame 10 is folded, the fixing portion 610 is accommodated in the snap-fitting portion 621 of the folding locking member 620, thereby locking the frame 10 in the folded state. The frame folding and locking mechanism 60 according to the present application further includes an elastic member 630 (shown in FIG. 8 ). In the embodiment shown in the figure, the elastic member 630 is a torsion spring, one end of which is fixed in the mounting recess 1211 of the rider seat 121, and the other end of which abuts against the folding and locking member 620, for example, abuts against the pivoting portion of the folding and locking member 620.

The following uses the example of the fixing seat 610 being arranged on the upper portion 132 of the front leg and the folding lock member being arranged on the upper portion 122 of the rider as an example to explain the operation process of the frame folding lock mechanism 60 according to the present application. Referring to FIG. 10 , FIG. 11 , and FIG. 12 , FIG. 10 shows the frame 10 in a completely folded state, FIG. 11 shows the frame 10 being unfolded from the folded state, and FIG. 12 shows the frame 10 in a further unfolded state.

As shown in FIG10 , when the frame 10 is in the fully folded state, the fixing seat 610 located on the upper portion 132 of the front leg is accommodated in the engaging portion 621 of the folding locking member 620 located on the upper portion 122 of the rider, and under the action of the elastic member 630, the engaging portion 621 always pivots in the direction of the fixing seat 610 (as shown by the arrow in the figure), so that the engaging portion 621 blocks the path of the fixing seat 610 moving along with the unfolding of the frame 10, thereby preventing the frame 10 from unfolding. Therefore, the frame 10 in the folded state can be locked to prevent the frame 10 from accidentally unfolding.

As shown in FIG11 , when the frame 10 needs to be unfolded, the thumb can be used to push against the pressure portion 623 (shown in FIG9 ) to overcome the elastic force of the button spring, forcing the engaging portion 621 to pivot in the opposite direction indicated by the arrow in FIG10 , so that the engaging portion 621 gradually and completely leaves the fixing seat 610, the folded and locked state of the frame 10 is released, and the operator can arbitrarily unfold the frame 10. FIG12 shows the further unfolded frame 10, at which time the engaging portion 621 is further away from the fixing seat 610.

Another embodiment of the frame folding locking mechanism 60' according to the present application is described below with reference to Figures 13A, 13B and Figures 14A, 14B.

First, the description is made with reference to FIG. 13A and FIG. 13B, which are schematic diagrams showing a child carrying device according to another embodiment of the present application. The frame folding and locking mechanism 60' of the other embodiment includes a pad 620' and a groove 610'. For ease of illustration, FIG. 13A shows a pad 620' located on one side, and FIG. 13B shows a groove 610' matching the pad 620'. The matching pad 620' and the groove 610' can be provided on both sides of the child carrying device, or can be provided on only one side. According to the embodiment shown in the figure, the gasket 620' of the frame folding locking mechanism 60' is arranged on the outer side surface of the upper part 122 of the rider, and the groove 610' matched therewith is arranged on the inner side surface of the upper part 132 of the front foot. Of course, it is not limited to this. For example, the groove 610' can be arranged on the outer side surface of the upper part 122 of the rider, and the gasket 620' is arranged on the inner side surface of the upper part 132 of the front foot.

Referring to FIG. 14A again, this figure is a schematic diagram showing a child carrier that is about to be in a fully folded state according to another embodiment of the present application. As shown in the figure, as the frame is folded, the pad 620' gradually approaches the groove 610', and when the frame is fully folded, the pad 620' will cooperate with the groove 610' to lock the folded state of the frame to prevent the frame from loosening and falling off. Specifically, referring to FIG. 14B, this figure is a cross-sectional schematic diagram showing the specific structure of another embodiment of the frame folding and locking mechanism. The groove 610' is provided with a first stopper 612', and correspondingly, the pad 620' is provided with a second stopper 622'. Specifically, according to the embodiment shown in FIG. 14A and FIG. 14B , the groove 610′ is formed inwardly at a substantially central position of the front foot upper portion 132, but the present invention is not limited thereto, and the groove 610′ may also be formed at a position slightly above the front foot upper portion 132. The groove 610′ is, for example, an elongated groove, the long side of which extends longitudinally along the front foot upper portion 132, and the side of the groove 610′ close to the ground is defined as the inner side, and the other side opposite thereto is defined as the outer side, then the first stopper 612′ may be formed on a long side of the groove 610′ close to the outer side, and the first stopper 612′ smoothly transitions with the front foot upper portion 132, so that the opposite second stopper 622′ can slide over the first stopper 612′. The long side of the groove 610' close to the inner side can be flush with the surface of the upper part 132 of the front foot or concave relative to the surface of the upper part 132 of the front foot; and the long side of the groove 610' close to the outer side, that is, the long side forming the first stop portion 612', can be slightly protruding or flush with the surface of the upper part 132 of the front foot. The gasket 620' can be, for example, a fixed washer protruding outward from the outer side of the upper portion 122 of the rider, so that when folded, the side of the gasket 620' close to the upper portion 132 of the front foot is the inner side, and the side away from the upper portion 132 of the front foot is the outer side. The second stopper 622' is arranged on the outer side of the gasket 620', and protrudes more from the outer side of the upper portion 122 of the rider relative to the gasket 620' as a whole, and smoothly transitions with the rest of the gasket 620'. The second stopper 622' extends along the longitudinal direction of the upper rider portion 122, and when the frame is folded, the second stopper 622' passes over the first stopper 612' along a direction substantially perpendicular to the longitudinal direction of the upper rider portion 122, that is, the extending direction of the second stopper 622' is substantially perpendicular to the direction in which the second stopper 622' passes over the first stopper 612'. The second stopper 622' is, for example, formed of an elastic body, and thus has a certain amount of deformability.

When the frame 10 is folded, the upper portion 122 of the rider pivots close to the upper portion 132 of the front foot, and accordingly, the pad 620' located at the upper portion 122 of the rider gradually approaches the groove 610' located at the upper portion 132 of the front foot. When the frame is fully folded, the second stopper 622' of the pad 620' passes over the first stopper 612' of the groove 610' along the arrow direction in FIG. 14B and then engages with the first stopper 612', thereby locking the folded state of the frame to prevent loosening and detachment. When the frame is fully folded, the longitudinal direction of the upper portion 132 of the front foot is close to being perpendicular to the ground, and similarly, the extending directions of the first stopper 612' and the second stopper 622' are also close to being perpendicular to the ground. Furthermore, when the frame is in the fully folded state, the frame folding locking mechanism 60' and the front and rear wheels are located at different front and rear sides of the frame, so that a better locking effect can be achieved.

When the frame needs to be unfolded, force can be applied in the opposite direction of the arrow in FIG. 14B to disengage the second stopper 622′ from the first stopper 612′, thereby allowing the upper portion 122 of the rider to pivot away from the upper portion 132 of the front foot, thereby unfolding the entire frame.

The frame folding and locking mechanism 60, 60' according to the present application has a simple and compact structure and does not occupy extra space. At the same time, it can ensure the folded state of the frame 10 to avoid accidental unfolding.

The child riding device 1 according to the present application may also be provided with a frame gripping mechanism 80, so that the user can grip the frame 10 when the frame 10 is fully folded, thereby lifting the frame 10 for easy carrying, thereby preventing the user from cutting his hands when lifting the frame 10, increasing the comfort of use and maintaining the clean appearance of the frame 10.

Figures 15 to 18B show schematic diagrams of a child riding device and/or its components according to another embodiment of the present application, wherein the driving member 510 is omitted in Figures 15 to 18B, but the connecting seat folding mechanism 50 of the child riding device of the embodiment shown in Figures 15 to 18B is the same as the connecting seat folding mechanism 50 of the child riding device of the embodiment shown in Figures 1 to 12, including the driving member 510 and the linkage 520.

In the embodiment shown in FIGS. 15 to 18B , the rider assembly 120 further includes a rider handle 126, and the rider handle 126 and the rider upper portion 122 are pivoted at a ninth pivot point S9. Referring to FIG. 15 , in the fully unfolded state of the frame 10, the pivot point (ninth pivot point S9) of the rider handle 126 and the rider upper portion 122 is located above the first pivot point S1. When force is applied to the rider upper portion 122 or the front foot lower portion 134 to collapse the frame 10, the rider handle 126 and the rider upper portion 122 are also pivoted and collapsed close to each other through the ninth pivot point S9. Referring to FIG. 18B , when the frame 10 is in the fully folded state, the first pivot point S1, the third pivot point S3, the fifth pivot point S5 and the ninth pivot point S9 are located above the second pivot point S2, and the third pivot point S3 and the fifth pivot point S5 are located in front of the first pivot point S1, the second pivot point S2 and the ninth pivot point S9.

In this embodiment, the rider assembly 120 further includes a rider seat 121, the rider seat 121 is pivoted at the ninth pivot point S9, and a tray 70 for accommodating items such as water cups is connected to the frame 10 through the rider seat 121. When force is applied to the rider upper portion 122 or the front foot lower portion 134 to fold the frame 10, the tray 70 rotates as the rider handle 126 and the rider upper portion 122 pivot and fold toward each other, and then forms an acute angle with the placement surface of the frame 10. Specifically, the tray 70 has a first side 701 (e.g., a top side) and a second side 702 (e.g., a bottom side) that are arranged opposite to each other, and the placement surface 71 of the tray 70 for accommodating items such as water cups is located on the first side 701. As shown in Fig. 15, when the frame 10 is in a fully unfolded state, the receiving surface 71 of the tray 70 is generally opposite to the wheels 20a, 20b and is generally parallel to the placement surface of the frame 10. As shown in Figs. 18A and 18B, when the frame 10 is in a fully collapsed state, the receiving surface 71 of the tray 70 is also generally opposite to the collapsed wheels 20a, 20b and is at an acute angle to the placement surface of the frame 10.

The frame gripping mechanism 80 is disposed on the second side 702 of the tray 70. As shown in FIGS. 14 and 17 , the frame gripping mechanism 80 includes a main body 81 and a connecting portion 82. The main body 81 is used as a handle for the user's fingers to grip, and the main body 81 extends along the left-right direction of the frame 10. Both ends of the main body 81 are fixed to the second side 702 of the tray 70 via two connecting portions 82. The two connecting portions 82 are, for example, elastic fingers, which are respectively engaged with two fixing holes 72 correspondingly disposed on the second side 702 of the tray 70.

In the fully extended state of the frame 10, the front surface 703 of the tray 70 conceals the frame gripping mechanism 80. Therefore, in the fully extended state of the frame 10, the frame gripping mechanism 80 does not affect the appearance of the frame. In the fully retracted state of the frame 10, the tray 70 forms an acute angle with the placement surface of the frame 10, so that the frame gripping mechanism 80 tilts downward and backward, thereby facilitating the user to lift the frame by grasping the frame gripping mechanism 80.
